Hmm could this problem also expose different as symptom?
I still receive dhcp from the isp and get a ip, but my internet is severely malfunctioning, if I visit github or go to this forum it gets extremely slow, it halts extremely long and then loads, but if I edit a post or write a post it again hangs, if it was dns which I think is not the problem due to caching, it must be something else.
If I look in speedtest all fine, when I look to ifconfig I see no error except maybe 2 on wired interfaces but doesn't increase.
It only happens to me to recent master builds, but I wonder if the DUID change can make this weird symptom too, it feels like the tx rate is severely degraded or something does DoS, when going back to a older firmware image I made with Jenkins on 17 feb the problem was not present.
